[[Bandai FCG board]]s are used largely by Bandai for ''Dragon Ball'' and ''Gundam'' games, as well as a few others. One Irem title uses it as well.


These boards contain one of Bandai's FCG mapper chips.
All of these games were originally assigned to [[INES Mapper 016]] before the subtle differences, that are nonetheless relevant for fully functional emulation, became known. Please refer to the [[INES Mapper 016]] page for a general description of all registers, and to the [[INES Mapper 153]], [[INES Mapper 157]] and [[INES Mapper 159]] pages for information on the differences of those particular mappers compared to mapper 16.
* [[INES Mapper 016]] submapper 4: FCG-1/2 ASIC, no serial EEPROM, banked CHR-ROM
* [[INES Mapper 016]] submapper 5: LZ93D50 ASIC and no or 256-byte serial EEPROM, banked CHR-ROM
* [[INES Mapper 159]]: LZ93D50 ASIC and 128-byte serial EEPROM, banked CHR-ROM
* [[INES Mapper 153]]: LZ93D50 ASIC and 8 KiB battery-backed WRAM, unbanked CHR-RAM
* [[INES Mapper 157]] (Datach Joint ROM System): LZ93D50 ASIC and 256-byte serial EEPROM on Datach Main Unit, optional additional 128-byte serial EEPROM on game cartridge, unbanked CHR-RAM, barcode reader

Bandai FCG boards are used largely by Bandai for Dragon Ball and Gundam games, as well as a few others. One Irem title uses it as well.

All of these games were originally assigned to INES Mapper 016 before the subtle differences, that are nonetheless relevant for fully functional emulation, became known. Please refer to the INES Mapper 016 page for a general description of all registers, and to the INES Mapper 153, INES Mapper 157 and INES Mapper 159 pages for information on the differences of those particular mappers compared to mapper 16.

  • INES Mapper 016 submapper 4: FCG-1/2 ASIC, no serial EEPROM, banked CHR-ROM
  • INES Mapper 016 submapper 5: LZ93D50 ASIC and no or 256-byte serial EEPROM, banked CHR-ROM
  • INES Mapper 159: LZ93D50 ASIC and 128-byte serial EEPROM, banked CHR-ROM
  • INES Mapper 153: LZ93D50 ASIC and 8 KiB battery-backed WRAM, unbanked CHR-RAM
  • INES Mapper 157 (Datach Joint ROM System): LZ93D50 ASIC and 256-byte serial EEPROM on Datach Main Unit, optional additional 128-byte serial EEPROM on game cartridge, unbanked CHR-RAM, barcode reader
